The plain-tailed warbling finch is a species of bird in the family Thraupidae. It is endemic to Peru.
Region
Andes Mountains
Typical Environment
Occurs in inter-Andean valleys and on arid to semi-arid montane slopes with scattered shrubs, cacti, and hedgerows. It favors scrubby hillsides, rocky gullies, and field edges, sometimes near human-modified landscapes. The species uses dense bushes for cover but will perch conspicuously to sing. It is typically absent from humid forest interiors, staying in open or shrubby habitats.
Altitude Range
2600–4200 m
Climate Zone
Highland

Beginner friendly: 1/5
This small tanager is restricted to high Andean valleys of Peru, where it frequents shrubby slopes and dry ravines. Its common name refers to the unmarked, uniformly dark tail that lacks the contrasting edges shown by some related warbling-finches. It often sings from exposed perches with a bright, musical warble. Recent taxonomic work places it in the genus Microspingus (formerly Poospiza).
Temperament
skulking but occasionally confiding near shrubs
Flight Pattern
short rapid wingbeats between low perches
Social Behavior
Often in pairs or small family groups; may join mixed-species flocks outside the breeding season. Nests are compact cups placed low in dense shrubs. Likely monogamous during the breeding period, with both parents involved in care.
Migratory Pattern
Resident
Song Description
A bright, sweet warble delivered from exposed perches, composed of short trills and clear whistles. Calls are thin, tinkling chips used to maintain contact in dense scrub.
Plumage
Generally dull gray-brown above with paler, slightly buffy underparts and subtle streaking or shading on the flanks. Tail is plain and dark without contrasting edges. Face shows a faint pale supercilium and dusky lores; wings show minimal or no wingbars.
Diet
Takes small seeds, buds, and berries, supplemented with insects and other arthropods. Forages by gleaning from low shrubs and grasses and by hopping on the ground to pick seeds. Insects are more frequently taken during the breeding season. Will visit weedy field edges and hedgerows where seeds are abundant.
Preferred Environment
Feeds in scrubby slopes, dry ravines with thorny bushes, and agricultural margins with scattered shrubs. Often stays close to cover, emerging to forage along edges and open patches.
